LINER.

Application filed June 23, 1924. Serial No. 721,855.

This invention relates to a method of forming nozzles and the like, and to the ar ticle itself, the general object of the invention being to provide a liner which is shaped to form the passage of the nozzle and then the body of the nozzle is cast around the liner so that the body can be formed of cheaper material than the material of the liner and the nozzle can be cast without using a core or core box, thus saving the expense of the same.

This invention also consists in certain other features of construction and in the combination and arrangement of the several 5 parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a plan view of anozzle made in accordance with this invention.

Figure 2 is a section on line 2--2 of Figure 1. Figure 3 is a section on line 33 of Figure 2. t

Figure 4 is asection on line 4-4 of Figure 5.

I Figure 5 .is an elevation of half of a sectional nozzle made in accordance with this invention. 35 y In these views, 1 indicates the body of a nozzle and 2 the liner which forms the walls of the passage 3 of the nozzle. In carrying out my invention I form the liner of material suitable for the purpose for which the nozzle is to be used and to be shaped to the desired form of the passage of the nozzle. Y The body is then cast around the liner and the exterior of the liner is so treated that it will knit with the body and thus form an integral part of the same. The-form shown in Figures 1, 2 and 3 has its body formed of a single part while that shown in Figures 4 and 5 is formed of two sections 4 and 5 which are adapted to be bolted together by bolts passing through the holes 6. In Figures 4 and 5 the liner is also formed of sections, as shown at 7 and 8 so that the interior of the liner can be buffed or otherwise treated after the parts are cast and before the two halves are bolted together.

It will of course be understood that the drawings simply show two types of nozzles shaped to produce the desired passage and having its meeting edges suitably connected together or 1t can be made of pieces of metal which are fastened together in any desired manner, such as by welding, riveting and the like. The liner can be cast or forged or machined from a solid block if desired. The body can be formed of the same metal or of different metals. Beforecasting the body the exterior of the liner is treated, such as by tinning, plating, soldering or the like so that it will knit with the body when the body is cast around it.

With this invention the liner can be made of metal which is acid resisting, wear and rust resisting and the like while the body is made at a cheaper metal so as to reduce the cost of manufacture of nozzles used for use with liquids or gases and the like. Before the body is cast the liner is packed with sand or the like so that it will retain its shape while the body is being cast around the same. A

The liner of the nozzle can be made of such material as will suit the work required of it. For instance, it may be made of nickel 'alloys, Monel metal, copper and the like. These materials are very hard to cast into shape but with this invention the liner can be made of any of the materials mentioned and then the body made of a metal which is easy to cast. Thus a nozzle can be made very cheaply which would be very ex-' pensive if the entire nozzle was made of the material from which the liner is made. It

also eliminates the use of a core box which tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the 5 combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claim.

What I claim is The herein described method of forming nozzles without the use of-a core or core box and comprisin in first forming a liner in the shape of t e passage desired and then casting the body around the liner.

In testimony whereof I afiix my signature.
